[Oomlout] has created an Arduino Experimentation Kit that uses basic sensors, buttons, and LEDs to teach electronics and programming. Printed overlays are secured on a breadboard, indicating components and connections. The Arduino is then used to drive the circuit. Examples include driving motors, using shift registers, and making beeps with a piezo element. These are backed up by explanations and code. The breadboarding kit is very similar to the classic 300-in-1 project kits marketed to beginners. In addition, all of the materials are released as open source. Kits are also available that include everything needed to create the circuits.

[oomlout] has released this Opensource robotic arm. It is 5 axis, using cheap hobby servos. The total cost, including having it cut at thingaiverse.com is roughly $150. The plans include all the pieces, down to the servo controller. This means that you’ll have to supply your own microcontroller and programming. They do state “We can guarantee it is loads of fun to play with, and we think potentially very useful for more serious pursuits.” and we would like to test that guarantee. We’ve been keeping an eye out for this ever since the servo switch assemblies.

If you are interested in trying out some home automation, but don’t want to get into the potentially dangerous area of hacking your house wiring, consider these servo switches. These allow you to flip a switch, using a servo. They are clean, temporary, and fairly compact. You can purchase them at oomlout.com or download the designs and build your own.
The team at oomlout has continued to post all the methods they use in their manufacturing process. This time around it’s the kitting process: how they actually packaged 30 identical SERB kits in an efficient fashion. We covered their wire cutting bot before, but they’ve got other dedicated machines like a sticker cutter. The stickers are used to remove all the cut acrylic pieces from the laser cutter as one unit. They’ve got some other tricks like using a scale to count bolt quantities, and an egg timer to keep track of the laser cutting. All of their envelopes are printed using a parallel port inkjet that has been modified to work with any thickness paper.
We love when hackers bother to post this much detail about their process. One of our favorites is [ladyada]’s full rundown of how the Minty Boost was created.
Kit builder oomlout—we’ve featured their servo bot—needed to produce a lot of precut wires. After cutting and stripping more than their fair share, they decided to apply some heavy engineering to make things easier. They constructed a machine to do the job for them. It has three main components: a servo driven wire feeder to measure the length, a two servo wire stripper that uses an exacto blade, and finally a wire cutter made from snips and a drill motor. The machine is controlled using an Arduino. They’ve published all the plans and code to Thingiverse incase anyone else wants to build a similar machine for their own kit shop. A video of the machine is embedded below.

When you’re prototyping a new project, sometimes all you need is a switch. The folks at oomlout were tired of constantly having to rewire things, so they built a universal switch box for the Arduino. It has five potentiometers plus three switches. They’ve put together a software package that monitors the switches and can show you a live view of the knob positions. Have a look at the video below for a demo.
The writeup actually hints at what we can only assume is the next kit they’re releasing: a robot arm. Continue reading “Arduino switch box”
oomlout has posted some interesting plans for a simple robot. It’s based around an Arduino and is a platform similar to the Parallax Boe-Bot. The Arduino sends PWM signals to continuos rotation servos that drive the two main wheels. All of the structural components are laser cut from acrylic with slots to hold standard hex nuts. It’s an interesting technique, but the design has a lot of potential for improvement. Right now it uses two different power supplies and a breadboard for simple connections. From the video below, you can see that the balance could be improved as well. Continue reading “Simple servo bot plans”
